Get config and register Listener.

If you want to pull it yourself when the program starts to get the configuration for the first time, and the registered Listener is used for future configuration updates, you can keep the original code unchanged, just add the system parameter: enableRemoteSyncConfig = "true" ( But there is network overhead); therefore we recommend that you use this interface directly
